Approaches to Management of Asthma: Guidelines for Stepped Care and Self-Monitoring.

While the twentieth century brought rapid changes to the diagnosis and management of asthma, consensus guidelines did not exist until the mid-1980s. Over the subsequent four decades, guidelines evolved from expert-based recommendations to comprehensive, evidenced-based references. The main two guidelines to be discussed in this chapter are the expert panel reports (EPR) published by the United States National Heart, Lung, and Blood Institute (NHLBI) and the Global Strategy for Asthma Management and Prevention Report (GINA) published by the NHLBI and World Health Organization (WHO). While these guidelines both focus on evidence-based approaches to the diagnosis and management of asthma, there are significant differences in both organization and recommendations. Just as the introduction of evidence-based guidelines was revolutionary to asthma management over the last 20 years, we anticipate further development of recommendations specific to precision medicine based on ongoing cutting-edge clinical research.
